I have an X bolt 243 here that ive just screwcut.
Havent shot it, here are my observations.
Synthetic bedding is poor - but at least it has some, unlike other brands.
Bottom metal is ally and looks decent quality, I particually like the use of cap head screws as standard.
Magazine is reasonably robust (nylon) and a good lock up in the bottom metal although I wonder how long the "lever" feed device will last.
Bottom metal and mag reminiscant of Steyr Prohunter..
Browning appear to have made the action so that only certain mounts fit it - each base has 4 6x48 screws - fiddly.
Bolt has three lugs - the example I have here only two are in contact with the abutments....
Like the M16 style extractor, bolt face recessed in bolt head - good safety feature.
Trigger, hmm
Washer style recoil lug, hmm
Looks a nice compact stalking rifle, however I think it has been built to a budget in some places.
